Gender equality metrics, eg. see the World Economic Forum report, generated from "hard" indicators:

where the top 3 countries are Scandinavian (4 if you include Iceland). On the same list, the UK is 13th, Australia is 21st, and the USA is 27th.

This list is consistent with my own impressions. You will also note the reasonably high correlation with the math gap list I referenced upthread.
